Description

Technical Field

[0001] The utility model relates to the technical field of lens detection, in particular to a device for detecting eccentricity of a rangefinder lens. Background Art

[0002] As a crucial component of a lens, the lens plays a crucial role in the overall imaging quality. Prior art methods for detecting decentration involve securing the lens to a rotating platform, which is secured with fixtures. An eccentricity detector is positioned above the rotating platform, which is then rotated for detection. This method requires the lens and the rotating platform to remain coaxial, and further adjustments are required when replacing lenses of different sizes, resulting in low detection efficiency.

[0003] After searching, the applicant discovered a Chinese patent disclosure for a "device for detecting eccentricity of a lens" with the publication (announcement) number "CN211717400U". This patent mainly adds a rangefinder to detect the horizontal offset of the lens. In the subsequent calculation process, the horizontal offset can be deducted from the eccentricity measurement value measured by the eccentricity detector to obtain the actual eccentricity of the side mirror. In this way, there is no need to set a centering device on the air-floating turntable, and there is no need for centering during the detection process. This will not cause wear on the outer circle of the lens, and the centering step is omitted, thereby improving the detection efficiency. However, this device is not conducive to detecting lenses of different specifications. Therefore, we propose a rangefinder lens eccentricity detection device. Utility Model Content
